These figures cover 263 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year
DL 1065 quarter by quarter
DL 1065 did not run the same all year. Its best quarter was Jan–Mar 2026 at 80.4% on time and its weakest Oct–Dec 2025 at 62.3%, a swing of 18 points on roughly 88 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 1065 did best on Thursday at 77.3% on time and worst on Sunday at 53.8%. Each day rests on about 38 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 1065
The latest arrival of the period was on 8 November 2025, 3 hours 57 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 November 2025 | 3 hours 57 minutes | Carrier |
| 9 November 2025 | 3 hours 14 minutes | Carrier |
| 19 July 2026 | 2 hours 59 minutes | Carrier |

Delay causes
Why DL 1065 runs late
Carrier accounts for 51% of the 3,929 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 35%Late-arriving aircraft
- 8%National Airspace System
- 5%Extreme weather
- 1%Security
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,929 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 3,929 delay minutes reported on DL 1065.
Cancellations run at 2.66%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
7.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 50 minutes, which a normal layover absorbs.
The 545 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on two other city pairs in the data, including ATL to CHA (8) and CHA to ATL (8), but none flew often enough under DL 1065 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to PBI only.
One caution: this is a thin sample. 263 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking DL 1065
For a booking, the cancellation rate is the figure to plan around on DL 1065: 2.66% of its 263 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
